High Precision CNC Machining Pressure Balancer parts

High Precision CNC Machining Pressure Balancer parts , It is the part of wiper system. For this part, Customer have good quantity demand. there are about 40K per month.  But for quality.should focus on the Brittleness Features: casting metal grain is too large or small, easy to break or fracture of the casting. Causes 1. Excessive overheating of alloy liquid or too long holding time. 2, the intense cold, . 3, aluminum alloy impurities zinc, iron and other content is too much. Exclusion measures 1, alloy should not overheat, avoid alloy long time insulation. 2, improve the mold temperature, reduce the pouring temperature. 3. Strictly control the chemical composition of the alloy. 4. Keep the crucible coating well  During actual production, the operator should work under the process parameters set up by the engineering according to the operation instruction. Visual inspect the condition of the castin…
